The hit rate is high, but either the cache is slow or the function is
not fast enough -- the cache no longer holds its weight, leading only to
very modest improvements. If it's the former, it can definitely be
improved, the code is very dumb (though it worked just as well as any
other I tried back then). But instead, let's just kill it.

We currently use strcasecmp, which is locale-dependent. In particular,
one well-known surprise even if restricted just ASCII input is found in
the tr_TR (Turkish) locale, see e.g.
https://msdn.microsoft.com/en-us/library/ms973919.aspx#stringsinnet20_topic5
We have known to avoid locale-dependent functions before, but in this
case, we forgot.
Fix it by implementing our own simple ASCII-only strcasecmp/strncasecmp.
Might have been possible to use strcasecmp_l() with the C locale, but
went the easy route.
Side advantage is that even this non-optimized version is faster than
the optimized libc one (__strcasecmp_l_sse42) since it doesn't need to
do the locale stuff. xkb_keysym_from_name(), which uses strcasecmp
heavily, becomes faster, and so for example Compose file parsing, which
uses xkb_keysym_from_name() heavily, becomes ~20% faster.

The current functions dealing with consumed modifiers use the
traditional XKB definition of consumed modifiers (see description in the
added documentation). However, for several users of the library (e.g.
GTK) this definition is unsuitable or too eager. This is exacerbated by
some less-than-ideal xkeyboard-config type definitions (CTRL+ALT seems
to cause most grief...).
So, because we
- want to enable alternative interpretations, but
- don't want to expose too much internal details, and
- want to keep things simple for all library users,
we add a high-level "mode" parameter which selects the desired
interpretation. New ones can be added as long as they make some sense.
All of the old consumed-modifiers functions keep using the traditional
("XKB") mode. I mark xkb_state_mod_mask_remove_consumed() and as
deprecated without adding a *2 variant because I don't it is very useful
(or used) in practice.
Alternative modes are added in subsequent commits (this commit only adds
a mode for the existing behavior).

In particular, highlight the use of configure flags to control locating
X11 keyboard stuff when building for Wayland.
Of particular note, if the locale root is not specified, then xkbcommon
will look for them under $prefix (i.e. /usr/local/share/X11/locale).
But unless the user has specifically installed them there, it is better
to look in the standard system location, /usr/share/X11/locale.
Otherwise, xkbcommon will error when it can't find them, e.g.:
xkbcommon: ERROR: ~/.XCompose:4:9: failed to expand %L to the locale Compose file
xkbcommon: ERROR: ~/.XCompose:4:12: unterminated string literal

Takes care of GCC's annoyingly persistent warn_unused_result warnings.
But it's better to avoid system() I suppose.

More meticulously free everything we create, including hooking up the
buffer-release callback so we actually free those when required. Make
sure seats are actually in the display's seat list.
The xkbcommon object-unref functions don't actually require
NULL-checking, so we can elide those.

interactive-wayland is very similar to x11/xev, and dumps out as much

It provides no titlebar and a completely random cursor, but such is

Instead of giving Doxygen a series of absolute paths to the source
files and a relative path to the output directory, run it from the
source directory with purely relative paths to the source files, and
give it an absolute path to the build directory.
This fixes the parsing of README.md with a separate build directory,
since the relative includes for doc/quick-guide.md and doc/compat.md
don't resolve otherwise. Doxygen's INCLUDE_PATH turns out not to fix
this either, since that's just a set of paths to open and parse, rather
than an analogue to cpp's -I.

For some reason, the dumped keymap started repeating the two key types
FOUR_LEVEL_PLUS_LOCK and FOUR_LEVEL_KEYPAD. I need to investigate, but
let's disable it for now until I do (the problem would likely not be in
the xkbcommon - at most in the test itself).

fileno() can fail, if called on e.g. fmemopen() FILEs which are not
backed by a file descriptor. This functions uses mmap to map the entire
file to memory, so using such FILEs will not work.
(There is actually no change of behavior here, since the following fstat
would have already failed with EBADF. But lets make it clear.)
Another possibility is to fall back to the !HAVE_MMAP case; but it
sounds like a better idea to leave it to the programmer to use the
new_from_string/new_from_buffer functions instead, instead of doing
double allocation behind their back.
